Abstract
Mo5Mn6Si8 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. there are five inequivalent Mo+2.40+ sites. In the first Mo+2.40+ site, Mo+2.40+ is bonded to seven Si3- atoms to form MoSi7 pentagonal bipyramids that share corners with seven MoSi7 pentagonal bipyramids, corners with three MoSi6 pentagonal pyramids, edges with three equivalent MnSi6 pentagonal pyramids, faces with two equivalent MoSi7 pentagonal bipyramids, a faceface with one MnSi6 pentagonal pyramid, and faces with three MoSi6 pentagonal pyramids. There are a spread of Mo–Si bond distances ranging from 2.62–2.73 Å. In the second Mo+2.40+ site, Mo+2.40+ is bonded to six Si3- atoms to form distorted MoSi6 pentagonal pyramids that share corners with five MoSi7 pentagonal bipyramids, a cornercorner with one MnSi6 pentagonal pyramid, corners with four MoSi6 pentagonal pyramids, an edgeedge with one MnSi6 pentagonal pyramid, edges with two equivalent MoSi6 pentagonal pyramids, faces with three MoSi7 pentagonal bipyramids, a faceface with one MnSi6 pentagonal pyramid, and faces with three equivalent MoSi6 pentagonal pyramids. There are a spread of Mo–Si bond distances ranging from 2.49–2.79 Å. In the third Mo+2.40+ site, Mo+2.40+ is bonded to seven Si3- atoms to form MoSi7 pentagonal bipyramids that share corners with seven MoSi7 pentagonal bipyramids,more »
